gouessej: The second code example in my previous post uses GLReadBufferUtil.write(File), which simply calls TextureIO.write(File). That internally creates a new BufferedImage every time, and has a noticeably worse performance than using AWTGLReadBufferUtil instead.

TextureIO shouldn't create a BufferedImage, maybe you make a confusion with AWTTextureIO or maybe TextureIO uses the default SPI based on AWT instead of our own encoders and decoders.
